Product Description
The emergency stopper, available for only one-time use, is designed to urgently stop in runway of the devices with an linear motor or servomotor.
Absorbs the energy using the plastic deformation of metal. Differs from the general hydraulic pressure shock absorber, impervious to an oil leak.
Designed more compact than a hydraulic pressure shock absorber with the similar absorption capacity.

4 Speed Controller

Also, a rebound, frequently seen in a rubber stopper, does not occur and the excellent absorption characteristics cause no damage to the device.

Emergency Stopper

1. Based on the equations for the selection, please calculate the kinetic energy (E1) of the application to be used and tentatively
selectthe model with grater maximum absorption energy than the calculated energy value.
↓2. Calculate the stroke of the tentatively selected model (St) based on the stroke equations and the table of coefficient for eachmodel, and calculate the thrusting energy (E2) using the equations for the selection.
↓3. Confirm that the total energy (E) and stroke (St) calculated above meet the specifications of the tentatively selected model.
When thespecifications are met, the selection is complete. If not, please calculate again with another model with greater
